Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a document processing apparatus and, more particularly, to a document processing apparatus for detecting and removing identifiable documents from a rapidly moving stream of documents, thereby ensuring secure placement of documents in the stream. The present invention relates to a document processing apparatus provided with a chain control device having a push member as a conveyance means for guiding a plurality of documents.

Printing of negotiable notes, bond certificates, stock certificates, and similar documents is generally accomplished by printing the paper on which those documents are printed. The paper is then visually inspected for printing defects. The inspector identifies the defective item and marks the defective item with fluorescent ink. These sheets are then cut and fed into a sorter where good sheets are separated from bad sheets before being sent to a numbering machine where a number is printed. After the paper is cut into individual documents, these documents are fed into a feeder and passed through a detector to detect defects.

Known device for examining bank drafts (UK patent no.
No. 1150605), grossly defective bank drafts are removed from the transport cylinder by a rejection cylinder and sent to storage, while good bank drafts remain in this transport cylinder and continue to move along their regular path.

Further, the known bank draft processing device (UK Patent Specification No. 898715) includes at least two sets of driven feed rollers that are interlocked with each other, and a gap between the rollers of the set other than the last set of feed rollers. The invention comprises a detection device for detecting bank bills exceeding a predetermined bill thickness or a bank bill becoming heavier, and a device for rejecting such bank bills. These ejectors are arranged in the bank draft feed path before the last set of feed rollers. Under the influence of the detection device, it prevents the defective bill from entering the gap between the rollers of the final set and deflects this bill into the hopper, while all other bank bills that are not to be rejected are They are fed into the nip of the final set of feed rollers to reach a collection device where these bank notes are stored. This known rejecting or deflecting device consists of a baffle plate or vane-like member which deflects the defective bank bill from its normal position, where it is not deflected, into the hopper so that it deviates from the normal feeding path. Can be tilted up to position by a solenoid.

Yet another document feeder (U.S. Pat. No. 2,804,974)
No.), when the document passes over the feed platform,
The defective document is conveyed to a vacuum guide wheel located below the carriage and projecting upwardly from an opening in the carriage, whereby the defective document is pulled down through the opening.
This known device does not have a chain control for transporting the documents, so that the documents cannot be reliably held.

In known deflection devices, rejected documents are sent to a receiving repository. However, it has been found that using a receiving repository to receive defective documents is impractical. Because the equipment must operate at high speeds, the bins fill up quickly and require almost constant driver attendance to unload the bins.

A principal object of the present invention is to detect discernible documents, such as those marked with fluorescent ink, with printing errors, from a high-speed stream of documents sent in hold by the chain control device. Documents that have been collected and have not been deflected and rejected are securely placed in a holding position and continue to move through the regular feed path provided in the chain device and sent to the next process, and documents that have been rejected are The documents to be rejected from the document flow are transferred from a first rotary vacuum suction body that sucks up the documents to a second rotary vacuum suction body that subsequently delivers said rejected documents to a delivery platform located along the flow from the vacuum suction device. The object of the present invention is therefore to provide a new and improved document detection and sorting means that is constructed so as not to require constant unloading of the repository.

Another object of the present invention is to provide a chain device having a push member as a conveying means for guiding a plurality of documents at high speed along a path having a predetermined positive holding device, a device for detecting an identifiable document provided therein; a first vacuum guide wheel provided above the chain device; and a second vacuum guide wheel provided above the first vacuum guide wheel; a pedestal disposed along the flow from the second vacuum guide ring for receiving the identifiable document; and a pedestal connected to the detection device and the first and second vacuum guide wheels to direct the vacuum to the first and second vacuum guide wheels. connected to vacuum guide wheels to upwardly remove the discernible document and send the removed document to the cradle, while both of the vacuum guide wheels are operated at high speed and the unremoved documents are a valve device operated to be held in reserve by a chain device, and a device for synchronizing the speed of the chain device and the peripheral speed of the first and second vacuum guide wheels;
An object of the present invention is to provide a new and improved document processing device comprising:

These and other objects of the invention will become apparent from the following description in conjunction with the accompanying drawings.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

Referring to Figure 1, documents a, b, etc. are on rail 1.
is fed in the direction of the arrow by a chain C having push members P1, P2, etc. This chain is attached to sprockets 8 and 9 (Fig. 3),
The sprocket is driven in the usual manner.

The excluded documents are made identifiable with fluorescent ink. The detector 2 is installed above the rail 1. This detector 2 is a common device for detecting fluorescent ink. Alternatively, alternating magnetic field detectors can also be used if the above-mentioned discernible document is made of a material that conducts eddy currents. Detector 2
a is a photoelectric detector used to detect overlapping documents, where one document is stacked in front of another. In such a case, the device is stopped by a command from the microprocessor 41. Detector 2b is another photoelectric detector configured to detect certain indicia placed on the document to determine whether the document is oriented correctly. Furthermore, photoelectric detector 2
c is a counter.

After passing through the detector 2, the document is sent between a first rotating vacuum guide wheel 4 having four vacuum suction ports 13, 14, 15 and 16 and an idler wheel 5. If it is detected by the detector 2 that it is to be rejected, the solenoid actuated valve 19 is actuated to connect the vacuum source to the vacuum guide ring 4. From there, the vacuum guide ring 4 discards the document to be removed and carries the document in a counterclockwise direction as shown in FIG.

The second vacuum guide ring 6 also has four vacuum suction ports 3.
7, 38, 39 and 40, and as soon as the vacuum in the vacuum guide ring 4 is released, the vacuum guide ring 6
The vacuum guide wheels 4 and 6 are arranged such that the vacuum suction port of the vacuum guide port communicates with a vacuum source to transfer the document from the vacuum guide wheel 4 to the vacuum guide ring 6. The document is then transported by vacuum guide wheel 6 in a clockwise direction as shown in FIG. 1 past a conventional counter 59. Further, the documents are sent to facilities 31-35 for discarding the excluded documents. That is, the document passes between rollers 31 and 32 and is transferred to an inner passage 33 extending above a moving belt 34, by which it is conveyed onto a pedestal 35.

In the vacuum guide ring 4, vacuum is supplied to the vacuum suction ports 13 and 15 by an outer arcuate vacuum slot 17. The vacuum suction ports 14 and 16 are connected to the inner arcuate vacuum slot 11. Slots 17 and 11 are connected to solenoid valves 19 and 19a, respectively. The vacuum suction port is placed in contact with the document near the leading edge of the document. Therefore, when something to be rejected is detected by the detector 2, the microprocessor 41 or other control device is triggered to turn on the connection to the vacuum via the solenoid valve 19, and the vacuum is turned on. It communicates with the arcuate groove 17. This arcuate slot 17 is provided in the fixed portion of the vacuum guide assembly so that a vacuum is applied to the vacuum suction port when it contacts the leading edge of the document to be removed. The vacuum is activated each time something to be removed is detected
It acts on the vacuum guide ring 4 through the electromagnetic valve 19 over a period of about 140° with respect to one rotation of the vacuum guide ring 4. The vacuum is then applied to the vacuum guide ring 6 for about 140 degrees around the vacuum guide ring 6 under the command of the microprocessor 41.

The assembly of the vacuum guide ring 6 also has an arcuate groove 3 for applying a vacuum to the vacuum suction port of the vacuum guide ring 6.
6 and 42 are provided. Approximately for one rotation
The vacuum acting on the vacuum guide ring 6 during 140° is the vacuum guide ring 4.
It acts later than when the document is inserted into the gap between the vacuum guide wheel 4 and the idler wheel 5. The arcuate groove 3 is arranged so that the vacuum suction port 37 discards the document and transfers it in a clockwise direction.
A vacuum acts on 6. When the vacuum spout 37 leaves the top of the arcuate slot 36, the vacuum is released and the document passes between rollers 31 and 32 and onto the delivery conveyor 34. The next vacuum suction 40 communicates with the inner arcuate slot 42 . The solenoid valve 10 is connected to the arcuate groove 42 of the vacuum guide ring 6 assembly, and the solenoid valve 10a is connected to the arcuate groove 36 of the assembly. All of the detectors and solenoid valves are connected to a microprocessor 41 or other control device.

If the next document is to be discarded, the vacuum is applied to the inner arcuate slot 11 via the solenoid valve 19a. The vacuum guide wheel 6 operates in the same way. Referring to Figures 2, 3 and 4, the second
The figure shows a side view of the assembly of the adsorption system. vacuum guide ring 4
is mounted on a shaft 24, which is driven by the driven gear 18. Shaft 24 is mounted within frame member F1, which frame member F1 is rotatably mounted relative to stationary side frame F by bearing assembly 43.
With this structure, the vacuum guide ring 4 can rotate together with the shaft 24 and the frame member F ₁ around the shaft 44 located at the axis of the bearing assembly 43.
The assembly of vacuum guide wheels 4 and 6 can be rotated away from the path of the document. Bearing assembly 43 also supports shaft 44 and
4 is equipped with an upper vacuum guide wheel 6, a driven gear 48, and another gear 52.

Power is supplied to the vacuum guide wheels 4 and 6 by a driven gear 45 a fixed to the shaft 45 , and the shaft 45 is connected to a gear 48 via a gear 46 and a timing belt 47 . The shaft 24 is also rotated via the gear 52 and the timing belt 51. The timing belt 51 is rotated so that the back side of the timing belt 51 is driven by the gear 52.
is connected between gear 18 and sprocket 50 (FIG. 3). Therefore, the vacuum guide wheels 4 and 6 rotate in opposite directions (FIG. 4). Idle sprocket 5
0a tensions the timing belt 47.

The suction ports 13 and 15 on the same diameter of the vacuum guide ring 4 communicate with the outer arcuate slot 17, while the other set of suction ports 14 and 16 communicate with the inner arcuate slot 11. The arcuate slots 11 and 17 are provided in a stationary valve plate 12 which is urged against the vacuum guide ring 4 by a spring 20 and prevented from rotating by a pin 53 mounted on the frame. (Figure 2).

The vacuum guide ring 6 is provided with two vacuum suction ports 38, 38a arranged in the axial direction of its circumferential surface at positions that are spaced apart from each other by a certain distance. Each of the vacuum suction ports is the vacuum suction port 13 of the first vacuum guide ring 4.
16, they are arranged at positions offset from each other in the axial direction. The vacuum suction ports 38, 38a provided on the same diameter of the vacuum guide ring 6 and the vacuum suction ports 40, 40a on the opposite side are connected to the fixed valve plate 5.
It communicates with an inner arcuate slot 42 provided in 4. The other set of vacuum suction ports 37, 38 communicate with the outer arcuate slots 36 in the same way as for the arrangement in the vacuum guide ring 4. Chains C and _C1 are mounted on sprockets 8 and 8' fixed to the shaft 45.
Chains C and _C1 are also operated by being attached to another set of sprockets 9 at the other end of the chain (FIG. 1).

Inner and outer vacuum arcuate slots should be provided. For example, assuming that arcuate slot 17 is evacuated and the first document is discarded, the arcuate slot is subjected to vacuum over approximately 140 degrees, which is more than a quarter turn. Therefore, if the second document is not supposed to be sucked up, and the next vacuum suction port also communicates with the arcuate groove 17 on the outside, the second document will also be sucked up, so the next vacuum suction port will be placed on the outside. It cannot communicate with the arcuate groove 17 of. Therefore, in this case, a groove other than the outer arcuate groove 17 is required, and for this purpose, the inner arcuate groove 11 is provided, and the vacuum suction ports of each set are alternately connected to the outer arcuate groove 17 and the inner arcuate groove. It communicates with slot 11.

The vacuum arcuate groove in the vacuum guide ring 4 is limited to an arc of approximately 140°. The vacuum arcuate groove in the vacuum guide ring 6 also defines an arc of about 140°. Therefore, when the detector 2 is activated, the solenoid valves 19, 19a
is the arcuate groove 17 or 11 in an area slightly larger than 140° formed by the arcuate groove 17 or 11.
Apply a vacuum to either. These solenoid valves are connected to the detector 2 via a microprocessor 41 or other control device, and
Processor 41 relays the detector signals over a rotation angle of about 140 degrees. Solenoid valve 10, 10a
The vacuum is applied to the vacuum guide ring 6 over an angle of about 140° later than the vacuum is applied to the vacuum guide ring 4. This vacuum is activated during approximately 140° of travel of the vacuum guide wheel 6 and is released at the end of this travel, and the document continues to fall, passing between rollers 31 and 32, into the guide path 33 on the conveyor 34. pedestal 35
leading to. The microprocessor 41 is synchronized by a signal generator 55 located on the shaft 45 of the chain drive sprocket 8 (FIG. 2).

Counter 58 (FIG. 1) counts the number of documents that are not sorted, and counter 59 counts the number of documents that are sorted. Detector 60 detects the doubled thickness of the document. When the thickness of the double flap is detected, the machine is stopped under the control of the microprocessor 41. Fluorescence detector 61 detects any document marked with fluorescent paint that has not been removed. Detector 61a is a photoelectric detector that checks the orientation of the document. These detectors are connected by cable D to microprocessor 41 (or other computer controlled device). E is a stop signal transmitter.

Figures 4A, 4B, 4C and 4D illustrate the operation of the device according to the invention.

FIG. 4A shows the document a being thrown away by the vacuum suction port of the vacuum guide ring 4. This document a has already been screened by the detector 2 and a vacuum has been applied to the outer arcuate slot 17.

FIG. 4B shows the state after one-fourth cycle has passed from the state shown in FIG. 4A. Document a is conveyed around it by a vacuum guide wheel 4. Assuming that the document b is not a document to be discarded, the vacuum suction port 14 is communicated with the inner arcuate slot 11, but the vacuum is not activated, since the document b should not be discarded.

FIG. 4C shows a state in which one quarter cycle has passed from the state shown in FIG. 4B. The document c is in a state of being thrown up by the suction port 15 communicating with the vacuum arch-shaped groove 17 on the outside. Document a has already been transferred to the vacuum guide wheel 6 and the vacuum arcuate groove 42
It is in a state where it is thrown up by the vacuum suction port 40 which is in communication with the vacuum suction port 40. Document B is not thrown away, but is reliably held on chain C for the next printing process.

FIG. 4D shows a state in which one quarter cycle has passed from the state shown in FIG. 4C. Document c is the vacuum suction port 15 communicating with the outer vacuum arcuate groove 17.
It is rotated and carried by. If the document d is to be discarded, the inner arcuate slot 11 is connected to a vacuum, which acts on the suction opening 16.
